Hi guys,


I need a help with this OC48X/POS-SR-SC.I need to hear your opinion about this.


I get a really strange ping result from this card, if I ping it with the datagram size 100 and around 5000 - 11000 (it's not an exact range), it will ping perfectly, but if I use another size than the one I mentioned above, it will not ping perfectly,


It's like there is an interval that is different for each datagram size (see the output below)


What do you guys think I should do with this card? Thanks!
